Featuring modern race geometry and an ovalized top tube for easy shouldering over obstacles, we’ve increased the Nature Boy’s mud clearance to eliminate unnecessary pit stops on the course. Built with an Eccentric Bottom Bracket to manage the chain tensioning, a shortened chainstay, and replaceable derailleur hanger, we’ve also outfitted the Nature Boy with a Columbus Futura carbon fork with adjustable rake, tapered head and steerer tubes, and clearance for 700c x 42mm tires.

With a fresh Fulton green and black splatter paint job, all the All-City custom touches you’ve come to expect star here too, including custom seat collar and dropouts, flat-mount brakes, and star reinforcements on the bottle bosses and fender mounts. For steel lovers starving for competition, these updates to the Nature Boy are destined to get you across the finish line faster than ever before.
